What Prospect Search gives you
Searching is nearly free
2 credits per search regardless of how many rows return, and zero when nothing matches. Iterate on your filters without watching a meter.
- 2 credits flat
- Free when empty
- Unlimited filter tweaks

Pay only for who you want
Every row carries an id. Reveal the handful worth contacting instead of buying a list where most records go unused.
- Reveal row by row
- 75 credits per reveal
- Free on a no-match
- No wasted list spend
Availability shown up front
Before spending anything you can see which rows actually have a work email behind them, so you never pay to discover a dead end.

Who uses Prospect Search
Outbound teams building a list
Define the ICP once as filters, see how many people actually match, and reveal only the decision makers you intend to contact this quarter.
Founders doing their own prospecting
No seat licence and no annual contract. Search until the filters are right, then spend a few credits on the ten people worth an email.
Agencies working across clients
Run searches for each client's ICP on one balance, and bill through only the reveals that client actually used.
Recruiters mapping a market
Size the talent pool for a role by title and seniority before committing to a search, then reveal the shortlist.
Frequently asked questions
What is a prospect search API?
It lets you query a B2B people database by job title, seniority, location and employer instead of looking up one person at a time. You get back a list of matching people, then choose which of them to spend credits revealing.
Why are last names masked in the results?
Search results are previews. Surnames come back partially masked and contact fields arrive as availability flags rather than values. That is precisely why the search itself is nearly free — you are paying to find the right people, not to receive their contact details. Revealing a row returns the full record.
How much does searching cost?
2 credits per search, no matter how many results come back, and nothing at all if a search returns no matches. Revealing a contact costs 75 credits and is only charged when a match is found.
What filters can I search on?
Job titles, seniority levels, person location, employer domains, employer headcount ranges, and free-text keywords. Filters combine, so you can ask for VPs of Marketing at 200-500 person companies in California in a single query.
Can I export the results?
Yes. Export the whole result page to CSV in one click, and any contacts you revealed during the session are included as extra columns in the same file.
Does it return direct dial phone numbers?
No. The reveal step returns verified work email, title, seniority and employment history. Direct dials are not exposed by this data source. If you need mobile numbers, use Mobile Finder instead.
